I don't know if anonymity is supposed to be the differentiator here, but true anonymity is not delivered by an end product -- it's essentially a "client side" concern.

The concept I was going for is discussion without identities. Maybe anonymity wasn't the right word.

Pseudonymity is probably the better term.

"Anonymous" is the right word, imo. "Pseudonymity" implies having a nickname (a pseudonym), which is not required to participate.
